Question

In the following exercises, solve each linear equation.$-\left(w-12\right)=30$

Short answer

The answer is$w=-18$

Step-by-step solution

Step 1. Given information

The equation is $-\left(w-12\right)=30$

Find value of w and check

Step 2. Calculation

Isolate w from the equation $-\left(w-12\right)=30$

$-w+12=30$

Combine like terms

$-w=18$

Multiply -1 on both sides

$w=-18$

Step 3. Check

Substitute $w=-18$in $-\left(w-12\right)=30$

$$\begin{gathered} -\left(\left(-18\right)-12\right)=30 \\ 30=30 \end{gathered}$$
